Someone should take the look what there is wrong. Someone sent non-working stick for me, but I wasn't able to reproduce issue. I used modulator to generate signal with just same parameters he said non-working, but it worked for me. It looks like e4000 driver does not perform as well as it should. Maybe I should take Windows XP and Linux, use modulator to find out signal condition where Windows works but Linux not, took sniffs and compare registers... But I am busy and help is more than welcome. regards Antti On 07/19/2013 02:50 PM, Jan Taegert wrote: > [1.] One line summary of the problem: > Kernel 3.8.x and later - DVB-T-USB-Device with module dvb-usb-rtl28xxu - > doesn't get signal on some frequencies > > [2.] Full description of the problem/report: > I am using a Terratec CinergyTStickRC (rev3), it's a usb-dvbt-device > with device-id: 0ccd:00d3. > Usually I am looking TV with vlc and use a channels.conf with 12 > channels, of which each four use the same frequency: 538 MHz, 594 MHz > and 618 MHz.
